Definitions
- the present invention relates generally to articulating doors for motor vehicles, and more particularly to a checkstrap assembly operative to positively locate a passenger door in an infinite number of positions between a fully open position and a closed position.
- passenger doors of motor vehicles are pivotally mounted to the vehicle body for movement between a fully open position and a closed position.
- Many such vehicle doors are designed to cooperate with a checkstrap which is operative for positively locating the door relative to the vehicle body. Additionally, on sloped surfaces, the checkstrap provides a mechanism to hold the door in its open position.
- a vehicle door will have an intermediate point between fully open and fully closed where the door will rest in a stable fashion. In situations where a space laterally adjacent to a passenger door prohibits the door from fully opening, opening of the door to the intermediate position may reduce incidents of unintentional damage.
- prior checkstraps for vehicle doors include a roller mounted to the vehicle body and an arm contoured to cooperate with the roller which is carried by the vehicle door.
- the arm is formed to include one or more camming surfaces.
- the roller functions as the cam follower.
- the cam surfaces of the arm and the roller cooperatively function to positively define an intermediate position at which the door may be located relative to the vehicle body.
- the common roller camming arm configuration provides one set intermediate position which the door can securely rest.
- the camming surface encourages the door to rest in one of the defined locations. This situation often requires operator to hold the door when the defined locations are not acceptable.
- the intermediate position may not be in an optimal location for a given situation. It may be desired to open the door securely in a position greater or less than the set intermediate point and leave it thereby unassisted.
- the present invention provides a checkstrap assembly for a door of a vehicle which is movable in relation to a door frame between a closed position and an open position.
- the checkstrap assembly includes an arm passing through an aperture in the door.
- the arm has a first end interconnected to a hinge fastened to the frame such that the door may be selectively moved relative to the arm.
- a second end is adapted to cooperate with a roller assembly within the door.
- the roller assembly includes a brake disk, carriage slot and guide. The roller assembly is configured such that the brake disk is always under load, which can be exerted through a spring, weight, magnet or equivalent.
- the load is exerted from the brake disk onto the supporting face within the housing which creates a braking force when the door is in a static state.
- the checking force is capable of overcoming the friction between the brake disk and the supporting face allowing free motion of the door.
- Carriage motion is predetermined by the guide which is affixed within the door.
- the arm pushes (pulls) the roller assembly across the guide causing the brake disk to move along the carriage slot and away from engagement with the inner wall.
- the brake disk tends to return to the central position which corresponds to the state of minimum potential energy and the state at which the brake disk is engaged with the supporting surface of the housing.
- FIG. 1 is an environmental view of a checkstrap assembly constructed in accordance with the teachings of the preferred embodiment of the present invention and shown operatively installed within a vehicle so as to interconnect a passenger door with the body of the vehicle;
- FIG. 2 a is an enlarged perspective view of a first embodiment of the checkstrap assembly of FIG. 1 removed from the vehicle for purposes of illustration;
- FIG. 2 b is an enlarged perspective view of a second embodiment of the checkstrap assembly of FIG. 1 removed from the vehicle for purposes of illustration;
- FIG. 2 c is an enlarged perspective view of a third embodiment of the checkstrap assembly of FIG. 1 removed from the vehicle for purposes of illustration;
- FIG. 2 d is an enlarged perspective view of a fourth embodiment of the checkstrap assembly of FIG. 1 removed from the vehicle for purposes of illustration;
- FIG. 3 is an enlarged perspective view of a fifth embodiment of the checkstrap assembly of FIG. 1 removed from the vehicle for purposes of illustration;
- FIG. 4 is an enlarged view of the roller assembly of the checkstrap assembly of FIG. 1, illustrating the brake position while moving the door between a fully closed and open position.
- the present invention provides an improved checkstrap assembly specifically intended for use with a passenger door of a motor vehicle.
- a checkstrap assembly constructed in accordance to the teachings of the present invention is illustrated and identified with reference numeral 10 as shown in FIG. 1 .
- the checkstrap assembly 10 is installed on an otherwise conventional vehicle 12 and functions to operatively interconnect a passenger door 14 of the vehicle 12 with the body 16 of the vehicle 12 .
- the intended purpose of the checkstrap assembly 10 to positively locate the door 14 in an infinite number of secure positions between a fully open and fully closed position will become apparent below.
- the checkstrap assembly 10 of the present invention is shown to generally include a locating brake mechanism 18 , a cooperating arm 20 and a mounting bracket 22 .
- a brake disk 19 is rigidly mounted to the cooperating arm 20 .
- the brake disk 19 is slidably mounted to a carriage slot 24 with a locating pin 27 .
- the carriage slot 24 is slidably mounted on opposite ends with roller units 26 that engage a guide 28 affixed to the support face 31 of the housing 30 .
- the housing 30 is suitably fastened to a forward panel 36 of the passenger door 14 .
- the mounting bracket 22 provides a ball joint connection to the arm 20 .
- the preferred embodiment includes a biasing device including a spring 32 and ball 34 suitably recessed in the housing 30 such that tension is continuously applied to the ball 34 travelling accordingly in a channel groove (not specifically shown) on the top of the arm 20 which in turn biases the brake disk toward the support face 31 of housing 30 .
- a torsion spring 40 is supported by the mounting bracket 22 connected to arm 20 . The torsion spring 40 biases the arm 20 and, consequentially, the brake disk 19 toward the support face 31 of the housing 30 .
- the arm 20 of the checkstrap assembly 10 is shown to include a first end 50 attached to the body 16 of the vehicle 12 . More specifically, the first end 50 , of the arm 20 is pivotally interconnected to the body 16 of the vehicle 12 through a ball joint connection with the mounting bracket 22 .
- the first position represents the brake disk 19 and arm 20 locations as the vehicle door 14 of vehicle 12 is being opened.
- the phantom line represents the brake disk 19 and arm 20 as the vehicle door 14 of vehicle 12 is being closed.
- the roller units 26 remain at the ends of the carriage 24 and traverse along the guide 28 as the vehicle door 14 is moved.
- a dynamic state results in the brake disk 19 rising up the carriage 24 thus avoiding contact with the support face 31 of the housing 30 and allowing for free movement of the vehicle door 14 .
